Embodiment Construction

[0016] With reference to the invention shown in the accompanying drawings, the design of the joystick structure among the present invention is intended to integrate braking, acceleration, and several manipulation structures to turn. At the same time, the structure can also provide a variety of manipulation feel. It can be selected according to the driver's personal operating habits and strength. For example, young people and old people, men and women can choose different driving feel.

[0017] Refer to attached figure 1 , 3 As shown, the joystick is connected to the base through a hinge structure, so that the joystick can rotate around the connection point. It ensures that the multi-degree-of-freedom movement of the joystick does not interfere, and at the same time simplifies the installation device of the joystick, avoiding the complicated and cumbersome structure of the rotating shaft. Just above the mounting hinges, install the cross support structure. This structure l...

Abstract

The invention provides a drive-by-wire automobile joystick structure which is suitable for multiple driving handfeel modes and integrates steering operation, braking operation and accelerating operation into a whole. The joystick drive-by-wire automobile control structure is characterized by being suitable for multiple driving handfeel modes, and the handfeel of a control system can be regulated according to the personal requirement of a driver. In the system, a joystick is of a two-freedom-degree angle output structure, wherein the transverse axis freedom degree corresponds to the steering operation, and the longitudinal axis freedom degree corresponds to the accelerating operation and braking operation. Magnetorheological dampers are arranged in the transverse direction and in the longitudinal direction, and the damping size of the magnetorheological dampers is controlled by an electronic control unit to regulate the handfeel during driving. In a device, the joystick is hinged to a box through a hinge, and a cross hollow support is arranged on the hinge to limit the joystick motion to be within two freedom degrees. Meanwhile, four sets of dampers and springs are installed in the cross support, wherein the dampers are used for regulating the control handfeel, and the springs are used for controlling a back joystick to be reset. At the tail end of the cross support, force sensors are connected with the springs to receive control information of the driver.

Description

technical field [0001] The invention relates to a control structure of a joystick-by-wire vehicle with multiple driving modes. Acceleration, braking and steering operations can be completed through this joystick. At the same time, its operation feel is optional. Background technique [0002] With the continuous development of automotive electronic technology and automatic control technology, wire control technology has become a research hotspot in today's automotive electronic technology and has a good development prospect. In the traditional mechanical system, the brake pedal, accelerator pedal, steering wheel and other operating structures are independent of each other, the structure is cumbersome, and it takes up a lot of space in the car. At the same time, the driver's manipulation of the traditional mechanical structure is complicated and labor-intensive. The control-by-wire technology breaks through the shackles of traditional mechanical structures, changes the driv...
